I want to align this family for earth pit with the surface of the road but align command don't work as the family hosted type 

so how can I align it with the road surface 

[mhiserZFHXS]

Does it have an offset from host parameter? If not, you'll need to open up the family to see what's going on with it.

[eng.girgis.adly]

no. there is no offset in the family

Is it a face based family?

[barthbradley]

Why not align it with the surface of the Host in the Family?  

[eng.girgis.adly]

I tried but it don't work 

even move up and down don't work

You should look in the Family editor, where is the reference plane "Center". Usually this one dictates the level /height of the element inserted in the project.

[eng.girgis.adly]

yes.

[eng.girgis.adly]

what should I do with the reference level ?

[anze.kumar]

The Ref. Level looks fine as it should be, but I suspect somehow it inserts your family 300 (your units) above the level. I do not know why as I do not have access to see how the family is built.
Maybe try lowering the box depth and see what happens, unfortunately this is probably not the permanent solution..

thanks dear for your support 

I tried it but still I can't align it to the hosted surface

Then I think the best next thing is to try and create a vertical (Height) parameter / offset from Ref. Level. 
- Create a reference plane

- Create a Dimension parameter ("Offset") from Ref. Level to said reference plane

- lock all the geometry (Extrusion of the box) to reference plane  at the bottom and Ref. Level at the top. 

- Try and stretch in Family Editor to see if it works properly

- Insert to project with Override parameters option

- Try adjusting Offset
